IMPROVEMENT IN WASH-BOILERS.

To ALL WHOM 1T. MAY oononnm Beit known that I, D. A. DANFORTH, ofElkhart, in the county of Elkhart, and 4State of Indiana, have inventeda. new and useful Improvement in Wash-Boilers and I do hereby declarethat the following is a clear,

full, and exact description of the construction and operation of-thesame, reference being had to the accom,v

panying drawings, making a part of this specification, in which- Figure1 is adongitudinal section of the'boilers, as indicated by line :o n: iniig. 3.

` Figure 2 is the same section as iig. 1, showing the inner boiler madewith flanges and without feet.

Figure 3 is a top or plan view, showing the inner boiler in the outsideboiler.

Like letters in the different figures of the drawings indicate likeparte.

It'has long been known that by `forcing a current of water continuouslythrough clothes or fabrics, for a. suiicient length of time, the dirtcontained in them will become dissolved and removed and .it is alsoknown that by-asuitable arrangement of devices, the water may be-thusforced through clothes placed in an ordinary wash-boiler, and theclothes thus washed or cleansed by the simple process of boiling; and toaccomplish this result in a simple and efficient manner, is the objectof my invention.

In the drawings, A represents the ordinary wash or clothes-boiler withwhich families are universally provided. Within this, I iit another orinner boiler, B, which is made of such a size as to leave a small spaceall around between the two.

The inner boiler, B, I construct with a slotted bottom, as represented,and turn down the edges of the strips on each side of the slots, so asto preventthe cut edges of the tin, in case that be used, from coming incontact with and soiling the clothes by rust, as is usually the casewhere a. .bottom having simply holes` or perfor-ations, is used, andthe'clothes permitted to rest on it. i

The inner boiler, I also provide with feet, D, upon which it rests, soas Vtoleave Va. :space underneath` it,`as shownin g. 1, or it may beprovided with an outwardly-projecting rim, d, to rest' upon acorresponding projection, b, on the inside of the outer boiler, as shownin tig. 2, and thus the boiler B be suspended within the outer one,leaving a smalll space between them all around. When thus suspended, theinner boiler should have -a seriesot holes, e, around its upper edge, asshown in g. 2, but when itis supported upon the feet, and the rim d isomitted, then the h'oles e may alsobe omitted, care being taken to makethe inner boiler somewhat lower than the other, as represented in figs.1 and 2. In such cases I prefer to have the projectioif b secured to theinside oi' the outer boiler, A, just above the top ofV the inner boiler,as shown in g. 1, this projection consisting cfa wire or narrow strip ofmetal soldered on, or it may be formed by striking up a bead around theboiler A, as is customary by tinncrs. i

To the inside of the inner boiler B, I secure a flange, E, vnear thetop,fas.represented, and also a handle, F, at each end, arrangedto turndown inside, to be out of the way of the cover, as shown in fig. 1.

' With the apparatus lthus constructed and arranged, the operation is asfollows:

A sui'licient quantity of water and soap is placed in the boiler, andthe clothes are then placeclin the inner boiler, B, and the cover puton. As soon as the water boils, it will ilow up the space between thetwo boilers, and run over the top or through the holes e, into theboiler B, and be deliected by the flange E inward towards the centre.and then pass down through the clothes therein, passing out through theslots in its bottom into the space underneath, where, becoming heated,it Vagain rushes up the surrounding space, and so ou continuously, aslong as the boiling continues, the flange E serving at the same time toprevent the clothes from rising around the edges, and thus'preventingthem from interfering with the inlowing currents at the top.

Bythis simple device and operation the clothes may be thoroughlycleansed, and the labor and wear of the usual rubbing process beentirely avoided. y

By making the inner boiler so that it can 'oc removed, `access isreadily obtained to all parts for thoroughly cleaning them, and at thesame time the outer boiler can bc used independently for all otherpurposes for which it is ordinarily required.

Having thus described my invention, what claim, is y y' it The innerboiler B, having its bottom slotted, and provided with iange E, arrangedto fit within and operate in connection with the boiler A, substantiallyas and forthc purpose set forth. l u
